Report Industry Investment Ratings - Copper: ★☆☆ (One star represents a bullish/bearish bias, with a driving force for price increase/decrease, but limited operability in the market) [1] - Aluminum: ★★★ (Three stars represent a clearer bullish/bearish trend and a relatively appropriate investment opportunity) [1] - Alumina: ★★★ [1] - Cast Aluminum Alloy: ★★★ [1] - Zinc: ★☆☆ [1] - Lead: ★★★ [1] - Nickel and Stainless Steel: ★☆☆ [1] - Tin: Not specified [1] - Lithium Carbonate: ★★★ [1] - Industrial Silicon: ★☆☆ [1] - Polysilicon: ★★★ [1] Core Views - The copper market lacks a clear guiding thread, with some underground copper mines in Chile resuming operations and waiting for the impact of tariffs. Hold short positions in the 2508 contract [2]. - The aluminum market shows narrow fluctuations, with the social inventory of aluminum ingots and bars increasing. The market is in a short - term shock, with resistance at 21,000 yuan. Cast aluminum alloy follows the trend of Shanghai aluminum, and the aluminum oxide market is in a state of surplus [3]. - The zinc market is pulled up by the external market due to continuous inventory reduction in LME zinc and increasing expectations of a Fed rate cut in September. The zinc price is expected to face resistance during the rebound [4]. - The lead market has insufficient fundamental contradictions. The supply and demand situation is complex, and it is advisable to hold long positions near 16,600 yuan/ton [6]. - The nickel and stainless - steel market is in the middle - to - late stage of a rebound, and it is recommended to enter short positions [7]. - The tin market is in a volatile state, and it is advisable to wait and see or take short - term long positions [8]. - The lithium carbonate market has a daily limit on Monday. The shutdown of a mining area in Jiangxi Yichun by CATL has affected the market, and the downstream is actively restocking [9]. - The industrial silicon market has significant supply pressure, and it is expected to show short - term shocks [10]. - The polysilicon market has a limited upward push in spot prices, and the trend may maintain a range - bound shock [11]. Summary by Metal Copper - Monday, Shanghai copper continued its upward trend in the session, with spot copper at 79,150 yuan and flat - water copper at a premium of 110 yuan/ton. Some underground copper mines in Chile resumed operations, and the market is waiting for the impact of tariffs. Hold short positions in the 2508 contract [2]. Aluminum & Alumina & Aluminum Alloy - Shanghai aluminum fluctuated narrowly, with the East China spot at a discount of 50 yuan. The social inventory of aluminum ingots increased by 23,000 tons and aluminum bars by 4,000 tons. The market is in a short - term shock, with resistance at 21,000 yuan. Cast aluminum alloy followed the trend of Shanghai aluminum, with a stable spot price of 19,800 yuan. Alumina is in a state of surplus, with limited downward space [3]. Zinc - LME zinc continued to reduce inventory, and the external market pulled up the domestic market. The term structure of zinc has flattened, and the inventory has increased. The zinc price is expected to face resistance during the rebound, and it is advisable to wait for short - selling opportunities above 23,500 yuan/ton [4]. Lead - The lead market has insufficient fundamental contradictions, with funds mainly reducing positions. The supply and demand situation is complex, and the social inventory continues to decline. It is advisable to hold long positions near 16,600 yuan/ton and pay attention to the maintenance rhythm of primary lead smelters in late August [6]. Nickel and Stainless Steel - Shanghai nickel rebounded, and the market trading was active. The upstream price support has weakened significantly. The inventory situation is complex, and it is recommended to enter short positions as the market is in the middle - to - late stage of a rebound [7]. Tin - Shanghai tin fluctuated and closed up, with spot tin at 268,000 yuan and a premium of 600 yuan to the delivery month. The social inventory decreased slightly last week. It is advisable to wait and see or take short - term long positions [8]. Lithium Carbonate - The lithium carbonate futures price had a daily limit on Monday. A mining area in Jiangxi Yichun by CATL shut down, and the downstream actively restocked. The total market inventory decreased slightly, and the price structure shows a weak near - month trend [9]. Industrial Silicon - Industrial silicon rose slightly, with stable spot prices. The market has significant supply pressure, and it is expected to show short - term shocks as the expected increase in downstream demand is less than that of industrial silicon [10]. Polysilicon - Polysilicon futures rebounded after reaching above 49,000 yuan/ton, and the spot price increase was limited. The downstream component price decreased, and the trend may maintain a range - bound shock [11].
